The Critical First Step for Many Bay Area Electrical Projects: PG&E Applicant Design is a process where a qualified, pre-approved designer (like GridSync) creates the engineering plans for your utility connection. You likely need it for any project that increases your electrical capacity—like a 200A panel upgrade, adding an ADU, or installing an EV charger. It’s the key to getting PG&E approval and avoiding project delays.

If you’re planning a major electrical project in the San Francisco Bay Area—whether it’s upgrading your home’s electrical panel, adding an Accessory Dwelling Unit (ADU), or installing a solar + battery system—you’ve likely encountered the term “PG&E Applicant Design.” It sounds technical, but it’s simply a crucial step in getting your project approved and connected to the grid.

Many homeowners and even general contractors are unfamiliar with this process, which is a leading cause of frustrating and costly project delays. This guide explains exactly what PG&E Applicant Design is, when you need it, and how partnering with a qualified designer like GridSync can save you time and headaches [citation:1][citation:4].

Bay Area Note

This guide is specific to projects within PG&E’s service territory, which includes San Francisco, San Mateo County, Santa Clara County, and most of the Peninsula. The rules and processes can differ for other California utilities like SCE or SDG&E.

SECTION 1

What is PG&E Applicant Design?

PG&E Applicant Design is a program that allows a pre-qualified, third-party designer—not PG&E—to create the engineering drawings and specifications for the utility-owned portion of your electrical or gas service installation. In short, a qualified firm takes on the responsibility of designing how your home will connect to the main power grid [citation:1][citation:4].

This program was launched in 2018 in response to a California Public Utilities Commission (CPUC) decision. The goal was to streamline the process for new and upgraded utility connections by distributing the design workload and ensuring high-quality plans from the start, which minimizes the number of back-and-forth reviews by PG&E [citation:1][citation:2].

What Does an Applicant Designer Actually Do?

A qualified PG&E applicant designer is responsible for a comprehensive set of technical documents. This is not a simple sketch; it’s a formal engineering package. According to PG&E’s requirements, the design must include [citation:1][citation:5]:

  • Detailed Drawings: Gas layout drawings, single-line diagrams (key sketches), base maps, construction details, and joint trench drawings.
  • Complex Engineering Calculations: These are critical and must be signed and stamped by a registered Professional Engineer (PE). They include calculations for voltage drop, flicker, short circuit duty, pulling tension, pole sizing, and guying [citation:1].
  • Material Specifications: A detailed material list for components like transformers, conduits, and meters, broken down by location and referencing PG&E’s rules (e.g., Rule 15, Rule 16) [citation:1].
  • Site and Permit Information: Identified rights-of-way, required permits, and coordination with other utilities [citation:1].
SECTION 2

How the Applicant Design Process Works

Understanding the workflow helps you see why a qualified designer is so important. Here’s a simplified step-by-step of the process [citation:4][citation:5]:

01

Application & Intake

You or your contractor submits an application for service through PG&E’s “Your Projects” online portal. PG&E assigns a representative (Job Owner) who will be your point of contact [citation:5][citation:9].

02

Design by Qualified Designer

Instead of PG&E designing the project, you engage a PG&E-qualified applicant designer (like GridSync). Our team visits the site, performs engineering analysis, and prepares the full design package, including all necessary drawings and calculations [citation:1].

03

Submission to PG&E for Review

We submit the completed design package directly to PG&E’s Resource Management Center. PG&E then reviews the plans to ensure they meet their current design standards and safety requirements. This review typically takes 1-3 weeks [citation:1][citation:5].

04

Approval & Proposal

Once PG&E approves the design, they provide you with a project proposal, contract, and an invoice for any applicable engineering advances or meter charges [citation:5][citation:9].

05

Construction & Inspection

After you sign the contract and make payment, construction can be scheduled. The physical installation is often done by a separate qualified contractor (an “applicant installer”) [citation:2]. After installation, local city inspectors and PG&E sign off on the work before your meter is installed and power is turned on [citation:5][citation:9].

SECTION 3

Do You Need It? Project Scenarios

Whether you need the full Applicant Design process depends on your project’s scope. In many cases, for a simple like-for-like panel replacement, you might not need it. But for any project that increases your home’s electrical capacity or requires changes to the utility service, it’s almost always required [citation:4].

✅ You Likely Need Applicant Design

200A or 400A Panel Upgrade: Increasing your home’s amperage nearly always triggers the need for a new utility connection design.
Adding an ADU: A new dwelling unit requires its own electrical service or a substantial sub-panel, demanding a new load calculation and utility design.
New Service for EV Charger: If your panel is at capacity and you need a new 40-50A circuit, this may require a service upgrade and therefore applicant design.
Overhead to Underground Conversion: Changing your service type requires a completely new design.
New Construction: Any new home build needs a new utility service design [citation:4].

❌ You May Not Need Full Design

Like-for-Like Panel Replacement: If you’re simply swapping an old 100A panel for a new 100A panel with no increase in load, you may qualify for PG&E’s “Express Connect” process, which is much simpler and faster [citation:4].
Small Repairs: Fixing a weatherhead or other minor service repairs usually don’t require a new design.

💡 Key Takeaway: If your project is on the left side of this list, you need a qualified applicant designer. Choosing one with in-house engineering, like GridSync, is the most efficient path forward. For a deeper look at the electrical work these projects entail, see our guides on 200-amp panel upgrades and ADU electrical requirements.

GridSync’s PG&E Design Expertise

The GridSync Advantage: In-House Qualified Designers

The most common source of project delays is a rejected PG&E applicant design. This happens when contractors without proper qualifications submit incomplete or incorrect packages. GridSync eliminates this risk because we are a PG&E-qualified applicant designer with in-house Professional Engineers. We handle the entire engineering process, ensuring your submission is accepted the first time [citation:6][citation:8].

PG&E QualifiedOur team has passed PG&E’s rigorous qualification program, meeting all requirements to prepare official designs [citation:1][citation:6].
In-House PE StampingAll critical engineering calculations (voltage drop, pole loading, etc.) are stamped by our registered Professional Engineers, a core requirement for any submission [citation:1][citation:8].
End-to-End ServiceWe don’t just design; we also coordinate with PG&E, handle permits, and can perform the physical installation as a licensed C-10 contractor, providing a seamless “design-build” experience.
Local ExpertiseWe know the specific challenges of Bay Area cities—from navigating Menlo Park’s permit office to designing for a steep slope in Los Altos Hills. We build this local knowledge into every plan.
Faster ApprovalsOur experience with PG&E’s current design standards, as detailed in the “Greenbook,” means your package is right the first time, shaving weeks off your project timeline [citation:9].
Complex Project ReadyWe specialize in the heavy-duty engineering—pole loading calculations, flicker studies, and pulling tension analysis—that contractors without in-house engineers often get wrong [citation:8].
SECTION 4

Applicant Design vs. Applicant Installation

It’s important not to confuse Applicant Design with Applicant Installation. They are two separate qualifications in PG&E’s program, and a company may be qualified for one, both, or neither [citation:1][citation:2].

RoleResponsibilityQualifications
Applicant DesignerCreates the engineering design, drawings, and calculations for the utility connection. This is the “planning” phase.Must pass PG&E’s qualification exam and demonstrate proficiency in design software, engineering standards, and PG&E’s specific requirements [citation:1][citation:6].
Applicant InstallerPerforms the physical construction work—trenching, laying conduit, setting substructures—according to the approved design and PG&E’s construction specifications (the “Greenbook”) [citation:9].Must be pre-qualified by PG&E through the Industrial Training Services (ITS) program to ensure they can safely build the utility facilities [citation:2].

GridSync is qualified for both. We can design your project and build it, providing a single point of responsibility and accountability. This avoids the finger-pointing that can happen when a design firm blames the installer or vice-versa.

SECTION 5

Frequently Asked Questions

QDoes PG&E charge for Applicant Design?
PG&E itself does not charge a direct fee for the design review, but you are responsible for the cost of hiring your own qualified applicant designer. This is a private contract between you and the design firm. PG&E’s charges typically come in the form of “engineering advances” and meter installation fees outlined in your final contract [citation:5][citation:9].
QCan my regular electrician do the PG&E design?
Only if they are a PG&E-qualified applicant designer. Many excellent electricians are not. If they attempt to submit a design without being qualified, it will almost certainly be rejected by PG&E, causing major delays. This is why it’s critical to verify this qualification upfront or work with a firm like GridSync that has it in-house [citation:6][citation:8].
QHow long does PG&E take to approve a design?
The review timeline can vary, but PG&E’s process maps suggest it typically takes 1-3 weeks for a complete and accurate submission [citation:4]. However, if the design has errors or is missing required calculations or stamps, it will be sent back for corrections, which can add weeks or months to your project. This is the primary risk that GridSync helps you avoid.
QI’m just adding an EV charger. Do I need a full applicant design?
It depends on your current electrical service. If your home already has a 200A panel with sufficient capacity, your electrician can likely install a new circuit without needing to involve PG&E at all. However, if the new EV charger requires you to upgrade your main service from 100A to 200A, then yes, that service upgrade will trigger the need for a new PG&E-approved design. For a detailed look at that process, see our guide on how to install an EV charger [citation:4].

Conclusion

PG&E Applicant Design is a specialized process that is often the critical path for any major electrical upgrade in the Bay Area. Understanding what it is and when it’s required empowers you to ask the right questions and hire the right professionals from the start. By choosing a qualified partner like GridSync, you aren’t just hiring an electrician; you’re hiring an engineering partner who can navigate the complexities of PG&E, ensuring your project gets designed, approved, and built efficiently.
